Central PA Late Spring 2012


Recommended Posts

The funny thing is, back in October, Hartford Ct ( Bradley ) which sits at a measly 160 ft asl, got 12" of snow with temps aroud 34 F.

Hopefully you should do ok once this storm really intensifies.

Yeah, I'm not to worried about it, should just be a matter of time. I'm hearing reports of power outages already in St. Mary's PA. My buddy lives there and he said quite a few people are out.

The NAM

but they just posted this in the discussion

.NEAR TERM /UNTIL 7 AM MONDAY MORNING/...

AN EXTENSIVE SHIELD OF RAIN /SOME HEAVY/ WAS PIVOTING TO THE

NORTHWEST AHEAD OF A POTENT SHORTWAVE PUSHING NORTH ALONG THE

I-95 CORRIDOR.

DUAL POL CORRELATION COEFFICIENT PRODUCT NICELY INDICATES THAT THE

PRECIP HAS CHANGED OVER TO WET SNOW AT THE BEAM HEIGHT OF

2500-3000 MSL JUST TO THE EAST OF THE RDA...WHILE THIS CC PRODUCT

AND SFC OBS INDICATES THAT THE CHANGEOVER HAS REACHED THE GROUND

ACROSS THE NW MTNS. KDUJ AND KBFD CHANGED TO SNOW BETWEEN 00Z AND

01Z...WHILE KFIG AND KJST JUST WENT OVER TO ALL SNOW WITHIN THE PAST

30 MINUTES. SOME WET SNOW FLAKES HAVE BECOME MIXED IN AROUND THE

HAPPY VALLEY AREA...AND A CHANGOVER TO HEAVY WET SNOW SHOULD OCCUR

FROM KAOO TO KUNV BETWEEN 03Z-05Z BASED ON THE 01Z RUC FCST OF MEAN

925-850 MB WET BULB TEMPS DIPPING SLIGHTLY TO JUST -0.5 TO -1C.

MIXED PHASE PRECIP IS NOTED AT ELEVATIONS AS LOW AS 4500 FT MSL TO

THE EAST THROUGH SSE /AT FURTHER DISTANCES AWAY FROM THE RADAR

SITE/...HIGHLIGHTING THE STRONG EAST TO WEST MID LEVEL TEMP GRADIENT

FROM THE CENTRAL MTNS TO THE SUSQ VALLEY.

THE SLOWLY DEEPENING AND DIGGING UPPER LOW HEADED OUT OF THE MID

OHIO RIVER VALLEY IS BEGINNING TO CAPTURE DEEP MOISTURE FROM THIS

LEAD SHORT WAVE...AS THE FLOW ALOFT CONTINUES TO BACK THROUGH THE

SOUTH AND BECOMES SERLY.

THE BACK /SWRN EDGE/ EDGE OF THIS CURRENT PRECIP SHIELD WILL

LIKELY EXPAND TO THE SW...AND PIVOT SLOWLY WWD ACROSS THE

COMMONWEALTH OVERNIGHT AND TUESDAY MORNING WITH PRECIP RATES BEING

MAINTAINED OR EVEN INCREASING ACROSS THE CENTRAL MTNS AND

ALLEGHENY PLATEAU...LEADING TO HEAVY WET SNOW WITHIN A FEW

QUASI-SNTRY BANDS OF MDT TO STG FRONTOGENESIS.

NO APPRECIABLE CHANGE WAS MADE TO THE GRIDDED FCST DATABASE WITH

RESPECT TO THE TIMING OF THE RAIN TO SNOW CHANGEOVER...AND

RESULTANT SNOW ACCUMS BY 12Z MONDAY. WILL BE KEEPING A WATCHFUL

EYE THOUGH ON THE HIGH TERRAIN OF SULLIVAN COUNTY /NE OF

KIPT/...SINCE THEY/RE CURRENTLY ONLY IN THE MID 30S WITH WEAK LLVL

COLD ADVECTION CONTINUING. HOWEVER...WARMER AIR SURGING IN ALOFT

FROM THE SSE SHOULD LIMIT ANY CHANGEOVER FOR MUCH OF THE NIGHT TO

JUST A MIX OF WET SNOW AND SLEET AT BEST.

Finally all snow, but its not doing much lol. I just saw CTP's new snowfall totals, ohhhhh man do I smell bigest forecast bust coming up. Kinda sad when KBFD goes from 20.1" to 5.1" lolololol

Wow! I read their discussion. Talk about a curve ball at the last second. State College will probably get a slushy inch if lucky. Looks like back home probably 4"-6" inches.

Man what a last minute and lame turn of events this is. We do have the deform shield starting to stabilize and establish about as expected, with the majority over the west central and UNV nearing the edge of the slot. The progressive turn on the models is going to take the big hitting and possibly historic option off the table and replace it with a more modest event with several inches in the highlands and perhaps a coating to a couple inches in the current advisory area. Still pretty impressive for this time of the year but now something that is not quite as unheard of. The intensity of this deform shield was crucial to getting a big event given the time of year, and with the turn to more progressive and less dynamic its going to really hurt accums.

Some morning musings from me. Given the forecasted track of the low I expected a pretty sizable dry slot to overtake the region east of the Susquehanna, and as of this mornings radar, those expectations were correct.

The lack of rainfall in my backyard was "a bit" of a surprise though. While we still got a decent amount (1.30") from the main part of the storm, it wasn't nearly as impressive as I'd originally thought. The heavier bands of precipitation acted eerily similar to past coastal snowstorms as they marched up through New Jersey and southeast PA, only to hit a proverbial brick wall before reaching the Tamaqua area. I could, on radar, literally watch the heavier echos "dry up" as they approached from the southeast.

While this certainly wasn't the drought buster some had hoped for, it still was a significant precipitation event, and some locations did actually do well. For those of you getting snow, I know you had hoped for the historical accumulations that the models have been showing, but in the long run, you may end up much better off with the lighter ones that I'm seeing some of you complain about. Your landscapes will be saved, and you most likely won't have to deal with the widespread, long duration power outages that were sure to have occured.

Do you guys still really want pics still, it is pretty much a non event so far. I have only accumulated 1.3" this morning for the obs total. This sucks.

Wish i could say that. Got rain and 35 degrees witht the rain/snow line actually moving away from me while ROC sees snow. Gonna be a HUGE bust here. Would be extremly lucky to get 1.3"

Snowing at a good clip here, just a dusting on grass.

Would be interesting to see the tops on Mt. Nittany/Tussey compared to downtown State College today. I would have to think those spots approach or reach warning snow amounts with the banding. The storm is going to be too progressive to really put down a lot of snow as it looked like yesterday and the day before, but any snow on April 23rd is very impressive. The tree damage would have been prolific as well. I was in town for the Blue/White game and saw all the leafed out trees. Many of them would have been destroyed if 4-8" of snow fell on them.

like normal, i question the reports on precip from Harrisburg. Yesterday it said Precip for Saturday was 0.0" wtf? It rained from about 2pm at least until i went to bed at midnight. it varied in intensity from complete downpour to mist. Now its says yesterdays precip was only .59" lol.

LOL Saussy....yes, I have no idea what MDT is reporting. They obviously got dumped on Saturday.

I've done very well so far with 2.46" of total precip since Saturday afternoon when it all began. I got 1.38" on Saturday and I know that blob of precip eventually passed over Harrisburg. We'll have to watch and make sure it gets corrected.

Meanwhile, 39 degrees here, a bit breezy, with light rain although we're on the western edge of the dry slot as it is rotating nw towards me. Looks like precip may shut off for a while. I wonder if the def band will simply collapse in place later today or actually progress eastward sending precip back over us????

Dont know if MDT is that far off...radar estimates do show low precipitation totals from MDT northward to IPT. Higher amounts are southwest and southeast (Lancaster County).

Well, they can say what they want, its BS. I don't have a rain gauge, but i will bet $$$$ we are well over 2" easily. It fricking dumped on Saturday, so much so areas here had flash flood issues.

My rain gauge showed 2.16" Saturday at 11 p.m. Considering it rained until about 1 a.m., starting raining again Sunday at 10 a.m. and didn't stop until about an hour ago, yeah they're way offbase.
